i got them because I enjoy modifying cars and believe lowering it will make my car less of a cookie cutter cruze rental car and give it a uniqueness about it. I also plan on doing other minor mods to make my car a fun, yet still economical daily driver.Spring kit for suspension, two are shorter for the front struts from left to right, left being #1, 1 and 3 for the rear, 2 and 4 for the front.
Now why did you get these? Replace broken ones, raise your Cruze a few millimeters, or lower it a couple?
Only other reason I can think of is to put all four under your gas pedal, this would definitely increase your fuel economy.
